Interconnect matrix RM0444
274/1390 RM0444 Rev 5
9.3.6 From RTC, TAMP, COMP1, COMP2, and COMP3 to LPTIM1
and LPTIM2
Purpose
RTC alarm A/B, TAMP1/2 input detection, COMP1/2_OUT and GPIO alternate function can
be used as trigger to start LPTIM counters LPTIM1/2.
Triggering signals
This trigger feature is described in Section 26.4.7: Trigger multiplexer (and following
sections).
The input selection is described in Table 134: LPTIM1 external trigger connection and
Table 135: LPTIM2 external trigger connection.
Relevant power modes
These interconnections operate in Run, Sleep, Low-power run, Low-power sleep, Stop 0,
and Stop 1 power modes.
9.3.7 From TIM1, TIM2, TIM3, TIM4, and TIM15, to COMP1, COMP2,
and COMP3
Purpose
Advanced-control timer TIM1 and general-purpose timers TIM2, TIM3, TIM4, and TIM15
can be used as blanking window input to COMP1, COMP2, and COMP3.
The blanking function is described in Section 18.3.7: Comparator output blanking function.
The blanking sources are given in:
• Section 18.6.1: Comparator 1 control and status register (COMP1_CSR) bits 20:18
BLANKING[2:0]
• Section 18.6.2: Comparator 2 control and status register (COMP2_CSR) bits 20:18
BLANKING[2:0]
Triggering signals
Timer output signal TIMx_OCx are the inputs to blanking source of
COMP1/COMP2/COMP3.
Relevant power modes
These interconnections operate in Run, Sleep, Low-power run, and Low-power sleep power
modes.
9.3.8 From internal analog sources to ADC
Purpose
Internal temperature sensor output voltage V
TS
, internal reference voltage V
REFINT
and
V
BAT
monitoring channel are connected to ADC input channels.
